Title: Propulsion systems
IPC: B60L13/03
Filed: 1971-07-07
Abstract: 1360834 Electric railways JAPANESE NATIONAL RAILWAYS 7 July 1971 [7 July 1970 25 Sept 1970 (2)] 31925/71 Heading B7L [Also in Division H2] A linear propulsion system for a movable body comprises a plurality of rectangular coils 1-1 ... 1-6, Fig. 1, vertically arranged along a horizontal path and a permanent or electromagnet 2 carried by the body for generating a magnetic field directed transversely of the coils so that when the coils are D.C. energized the horizontal portions thereof produce a lifting force on the body and certain of the vertical portions produce a driving force along the path, switching means being provided for energizing selected coils in the region of the body as it moves along the path. The magnet core may be C-shaped so as to utilize only one horizontal portion of each coil to produce lift or two opposing C-shaped cores may be located on opposite sides of the coils so that both horizontal portions thereof may be utilized, Fig. 5 (not shown). In the embodiment shown in Fig. 6(b), two lines of interconnected coils 1<SP>1</SP>, 1<SP>11</SP> are mounted in parallel on a track 14a and co-operate with an E-shaped electromagnet 2a carried by the body 6. The coils are connected to lines of conductive segments 9, 10, each coil having a segment located opposite to it, and current is supplied to the segments by roller contacts 11, 12 carried by the electromagnet and which connect the segments in turn to bus-bars 8, 9 as the body moves. The contacts are staggered relative to each other in the longitudinal direction so that a selected span of coils is energized at a given time, and to vary the position of the span with respect to the electromagnet to change from a driving condition to a coasting or braking condition, the roller contacts are mounted on motor-driven threaded rods 11<SP>1</SP>c, Fig. 6c, so that they can be displaced in the direction of movement of the body. Guide rails 15 for the electromagnet are provided at the sides of the track on which the electromagnet rests when deenergized. As shown, the bus-bars and contactsegments are mounted centrally of the track but they can be located externally of the electromagnet adjacent the rails 15, Fig. 6d (not shown). Also, the coils may be arranged in overlapping relation instead of being end-toend, Fig. 8 (not shown). In a further embodiment, Figs. 10 and 11 (not shown), the coils are connected to the bus-bars through thyristors mounted on the track and turned on and off sequentially by transducers responsive to signals, e.g. light signals, emitted by generators carried by the electromagnet in place of the roller contacts 11, 12, the generators being adjustably mounted similarly to the roller contacts.

Filed: 1956-10-22
Abstract: 851,356. Feeding cigarettes into receptacles. PEMBROKE, G. F., and MOLINS MACHINE CO. Ltd. Oct. 22, 1957 [Oct. 22, 1956], No. 32092/56. Class 94(1). Apparatus for collecting cigarettes comprises a support 2 movable past a fixed guide 7 down which cigarettes flow to stack on the support between a front 3 and rear wall 4, the rear wall being moveable past the guide as the support progresses forward during loading and also being moveable relative to the front wall 3 so that it may be withdrawn and replaced in a different position relative to the front wall after the collected cigarettes have been removed and the support has moved rearwards to bring the front wall against the rear wall. Cigarettes are supplied by catcher bands 1 to ribbed members 11, 12 which are oscillated by eccentrics 13 to feed the cigarettes downwards to a stack maintained at an approximate level 26 by photoelectric means 27. The means 27 causes interruption of the drive of the collecting apparatus if the level falls beneath it. Levelling members 18 are oscillated by eccentrics 19. The support 2 is moved forwards and rearwardly by slow and fast feed screws, Fig. 8 (not shown), and has the wall 3 fixed to its forward end. The rear wall 4 is mounted independently of the support on horizontal and transverse slides, Fig. 8 (not shown), and is slotted to enable forked portions of the guide 7 to pass through it. Loading commences at the position of Fig. 1 with the rear wall stationary and the support moving forwards as the cigarettes accumulate. Eventually a stop 9 on the support engages a projection 8 on the wall 4 and carries it past the guide 7. At the most forward position, a plunger 10 moves all cigarettes between the walls 3 and 4 into a collecting tray T, Fig. 4, and the support retreats, the wall 4 remaining stationary until contacted by the wall 3. It then removes sideways, backwards and forwards again to take up the position of Fig. 1 leaving the residue of cigarettes between the members 3, 7 as shown by the chain dotted line. Collecting may now recommence. According to the Provisional Specification, the catcher bands may be as described in Specification 820,845.

Title: Stepped pulley drive, particularly for ring spinning machines
IPC: D01H1/20
Filed: 1927-12-02
Abstract: 290,524. Maschinenfabrik Oerlikon, (Assignees of Hildebrandt, J.). June 8, 1927, [Convention date]. Driving-arrangements.-In a stepped pulley drive particularly for ring spinning-machines, for example of the kind described in Specification 267,550, [Class 80 (ii), Gearing, Variable-speed &c.], 'the belt is shifted by means of a screwed shaft 18 driven from the rollers through reversing-gear, which is controlled by the ratchet gear of the building-motion so that it is abruptly disconnected when the belt reaches its extreme positions. Two relatively adjustable discs 1, 2 are mounted on a shaft 43 driven from the ratchet wheel pin 6 of the building-motion and are provided with notches 1', 2<1>, which, during the rotation of the shaft 43, permit levers 10, 9 to be moved by a spring 7 and engage clutches 13, 12 whereby a shaft 11, driven from the roller shaft, actuates the shaft 18, so that the nut 20 of the beltshifting gear 13 is moved in one or the other direction. During the formation of the cop bottom the lever 9 and clutch 12 are engaged and the shaft 18 is rotated so that the belt-shifting gear is moved to the right, Fig. 2, and the belt placed on the large pulley 32, whereupon a cam 26 on an arm 30 of the belt-shifting gear lifts a detent 29 and allows a spring 22, which by this movement has been compressed between the rod 30 and a stop 25, to force a rod 24 which carries the stop to the right so that an oblique surface 28 thereon actuates the lever 9 and removes it from the notch 2<1> and disconnects the clutch 12. When, in the course of the building of the cop, the lever 10 is engaged with the notch 1<1> and the clutch 13 is engaged, the shaft 18 is rotated in the reverse direction and the belt moved on to the small pulley, the cam 26 acting upon a detent 39 and compressing a spring 23, in the same manner as the detent 29 and spring 22 are operated, so that the rod 24 is moved to the left and the lever 10 is disconnected by the oblique surface 27. When the bobbin is completed and the operative turns back the ratchet-wheel pin 6 the discs are reset in the starting position. During the resetting, the lever 10 is withheld from the notch 1<1> by the oblique surface 27, and the lever 9 engages the notch 2<1> and passes therefrom by reason of a spring-controlled tooth 41, Fig. 5, arranged within the notch. A leather disc 33 is interposed between the discs, and the disc 2 is secured by a nut 44. The adjustment of the disc 1 is effected by rotating the worm 4 when the shaft 5 is disconnected.

Title: Photographic compositions
IPC: C08F291/18
Filed: 1960-09-23
Abstract: 959,034. Photographic materials and processes. HORIZONS Inc. Sept. 23, 1960 [Sept. 28,1959], No. 32826/60. Heading G2C. A photographic light-sensitive material comprises a layer of a film-forming resinous binder containing an N -vinyl derivative of an organic nitrogen compound and an organic halogen compound which produces free radicals on exposure to light (including ultra-violet radiation). The layer preferably contains also an arylamine. The layer produces a print-out image on prolonged exposure, but a brief exposure gives a latent image which may be developed by heat or infra-red radiation, which treatment also serves to fix the image. The N-vinyl compound may be the N-vinyl derivative of indole, carbazole, phenyl-α-naphthylamine, pyrrole, pyrrolidone, diphenylamine, succinimide, phthalimide, N-phenylacetamide, N-methylacetamide or diglycolylimide. The organic halogen compound may be carbon tetrabromide, iodoform, hexachloroethane, hexachlorobenzene, tetrabromobutane or tetrachloro-tetrahydronaphthalene, and the arylamine may be diphenylamine, dibenzylamine, triphenylamine, diphenylguanidine, triphenylguanidine N; N-dimethylaniline, N; N-diethylaniline, p; p<SP>1</SP>-methylenebis (N; N-dimethylaniline), p; p<SP>1</SP>-benzylidenebis (N; N-dimethylaniline), p; p<SP>1</SP>; p<SP>11</SP>-methylidyne-tris (N; N-dimethylaniline) or a mixture of aniline and o- and p-toluidine. In one variation, a direct positive image may be produced by giving the material a brief exposure to light followed by an imagewise exposure to heat or infra-red. The latter exposure may be effected by placing a typewritten copy with its lettering against the sensitive surface and wrapping it round a rotatable drum with the back of the copy uppermost, a heating coil being arranged above the surface of the drum. In a further variation, the sensitive material is first given an imagewise infra-red exposure and then a uniform exposure to light to print-out the image in the non-infra-red exposed areas. In either of these variations,the light-sensitive layer should contain a sulphur compound such as thiourea, thioacetamide, thiocarbanilide, dodecanethiol or zinc sulphide so that the image may be fixed by exposure to moist air as described in Specification 941,488. The light-sensitive layer may contain an azo compound as sensitizer a a plasticizer or an ultra-violet absorber. Specifications 916,779 and 959,033 also are referred to.

Title: Improvements in and relating to high frequency heating apparatus
IPC: H05B6/04
Filed: 1945-12-06
Abstract: 608,247. Induction heating. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 6, 1945, No. 33034. Convention date, Dec. 9, 1944. [Class 39(iii)] A heating coil 1 mounting a work piece 2 of magnetic material has an inductance 3 connected in parallel presenting a low impedance alternative current path. When the work piece reaches its decalescent temperature and the rate of heating consequently falls to a low value, a brass plunger 4 is withdrawn from the inductance coil 3 by a solenoid 5 so that a high impedance alternative parallel current path is presented and all the high frequency energy is caused to flow in the heating coil, with rapid heating of the work piece continuing after the decalescent temperature has been reached. Automatic movement of the plunger 4 by the solenoid 5 is arranged at the desired point in the heating cycle by the provision of two cathode resistors 26, 27, such that the grid of a discharge device 24 is maintained at a negative potential with respect to its cathode sufficient to prevent the device from conducting. A condenser 22 is charged through a rectifier 30 by the volt drop across 26. When the power imput to the heating coil falls below a predetermined value with proportional decrease of volt drop across resistors 26, 27, the reduced negative potential on the grid of 24 allows the discharge of the condenser 22 to take place through a relay coil 23 and the valve 24, thus actuating the solenoid 5 which is then held in position by a holding circuit through switch contacts 32.
